Hydrodynamo Shaft is a room in the Torvus Bog in Metroid Prime 2: Echoes. It is a small, round room that features many flights of stairs. Through grating the Alpha Blogg is visible. There is a Portal on a higher ledge that can be reached with the Gravity Boost or by performing a Ghetto Jump.

The Dark Aether version of this room was the Undertemple Access.
